In studying evolution, the common characteristic can be compared to find out how much variability exist among species. An ex in vertebrate species is the number of differentiations in hemoglobin.
The follow table compares hemoglobin from other species to that of the humans;
Species of different Amino Acids Estimate millions of years from the common ancestors
Rhesus monkey 8 26
Mouse 25 80
Chicken 45 275
Frog 70 330
Lamprey 125 450
a) Find out the average number of years per mutation in the hemoglobin for each species listed?
b) Find out the mutation rate in mutation per million years for each species.
c) Which animal demonstrates a mutation rate closet to the average?
d) What percentage of amino acids is different from humans in monkey and lamprey?
